Honestly I had a really hard time recognizing this as a shojo manga. There was so much fanservice - numerous panty shots or almost naked scenes and it seemed like half of the panels were close ups of our lead female making erotic faces. Aside from the main male character, there were no bishounen. In fact, most of the other males barely stood out as characters.

The lead female is a lolita and an airheaded with basically no personality except that she is completely in love with the prime minister's son. I was expecting more from her since she is supposedly a genius, but all of
her work and achievements are clouded by her desire for the guy. She is very disappointing as a main character. I think the only reason I was able to get so far is because I like the lead male character, an outwardly cold (borderline sadistic) personality type with a soft interior.

In short, this manga really disappointed me. I think the only chapter worth reading was the first one, after that it turns into something that reads more of a borderline ecchi (or maybe full-blown, idk) manga than a shojo one.
